RDIoT Demo

4 Channel IR Tracking Module [S075]

https://www.youtube.com/watch?v=MOsxmBge2wU

*GitHub : https://github.com/rdiot/rdiot-s075.git

* Specs

Working voltage: DC 3.3V-5V

Working current: try to choose more than 1A power supply

Working temperature: - 10oC - +50oC

Mounting aperture: M3 screws

Detection range: 1mm to 60 CM adjustable, the closer the performance more stable, white reflects the farthest distance.

Size: in the control panel of 42mm * 38mm * 12mm (length * width * height)

Small forward 25mm * 12mm * 12mm (length * width * height)

Output interface: 6 wire interface (1234 to 4 signal output ends, + positive power, - for the negative power is ground)

The output signal: TTL level (can be directly connected to I/0 microcontroller, infrared light reflected back to the sensor induction, the red indicator light, output low level; no infrared light, the indicator light does not shine, the output high.)

*GitHub : https://github.com/rdiot/rdiot-s026.git

* Specs

Operating voltage: 2.5V - 12V(cannot over 12V)

Working current: 18mA - 20mA at 5V

Output electrical level signal: low level when detecting objects / high level when no objects / 0 or 1 decides if objects exist.
